Performance of chest compressions with the use of a new audio-visual feedback device: A randomized manikin study in health care professionals

摘要

Aim: Optimal depth (50-60 mm) and rate (100-120 min(-1)) of chest compressions (CC) is the prerequisite of effective cardiopulmonary resuscitation (CPR). However, insufficient CC during CPR are common even among health care professionals. We sought to evaluate if CC are more effective with the use of a novel feedback device compared to standard CC. Primary endpoints were absolute percentage of correct CC of all CC (correct rate and correct depth, classified as "optimal" CC), and the percentage of CC in target rate and percentage of CC in target depth.
